` froBAcco PIPE.`

Application filed November 15, 1920. l SeriaI No.y 424,176.

To all whom z5 mag/concern:

Be it known that I, lViLLrAM R. DALns, a .citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful` Tobacco Pipe, of which the following is a specification.

This invention relates to tobacco pipes, one of its objects being to provide a pipe stem of f novel construction having means combined therewith whereby saliva is prevented from flowing into the bowl of the pipe so that the pipe will not acquire the disagreeable odor resulting from the flow vof saliva to the bowl.

A further object 1s to provide means of this character which will in no way inter-` fere with the draft through the pipe.

A still further object is to provide means upon the mouth end of the stem for spreading the smoke in all directions within the mouth.

With the foregoing and other objects in view lwhich will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings the preferred form of they invention has been shown.

1n said drawings- Figure l is a side elevation of a tobacco pipe embodying the present improvements.

Figure 2 is a longitudinal section therethrough.

Figure 3 is a bottom plan view of a portion of the stem.

Figure 4 is an enlarged section on line 1 -ll, Figure 2.

Referring to the figures by characters of reference l designates the bowl of the pipe having the usual integral stem 2 provided with a smoke passage 3. The part 4L is adapted to be connected to the stem 2 in the usual manner, as by means of a threaded projection 5 and this part'constitutes the mouth piece ofthe pipe. The bottom portion of the mouth piece is cut away adjacent the rear end so as to form a depression 6 having a flat rearwardly extending wall 7. A passage 8 is formed in the mouth piece and eX- tends from the inner portion of the depression 6 'andd through the projection so as toy register with the passage 5. Ashort neck 9 is formed at the back end of the mouth piece and carries a flange 10 forming a smoke spreading shield, the upperportion of this flange slightly overhanging the month piece asy shown. i ,i Y

Fitted on the stem 2 and thevmouth. piece 4 `is a sleevev 1l formed `preferably of^ softl rubber, this sleeve. projecting toward the neck9 and bei'ngprovidedinits upper and lower portions at the rear end with suitably L-shapedrecesses 12. rThis sleeve, whenin position, fits ltightly about the ,stema2 and the front portion of the mouth piece and also extends completely overA or across the recess Gand .bearsfirmly upon the flat -wall 7 ofv the recess. Consequently when themouth piece is A,held inthe mouth saliva cannotflow into 4the passage `8.because the back end of the sleeve 11 jwill` seal the .recess 6 and the passage 8. Vlhilesmoking, the user, in drawing upon the pipe will suck the smokev from the rear end of the passage 8 and from the recess 6 and out through the back end of the sleeve l1 which, obviously, will be opened out to allow the smoke to pass into the mouth. As soon as the suction ceases, however, the sleeve will close against the wall 7 of the recess 6 so as to prevent saliva from flowing into the recess and into the passage in the mouth piece. As the smoke is drawn out of the back end of the sleeve 11 it will strike against the flange 10 and be scattered in all directions by the flange, portions of the smoke flowing upwardly around the neck 9 so that the smoke will thus be spread throughout the mouth and prevent irritation of the mouth.

Not only is the sleeve 11 advantageous for the reasons hereinbefore pointed out, but it is also desirable because it prevents the smoke from escaping through the mouth piece after the same has been removed from the mouth. v

While the device herein described is primarily designed as a tobacco pipe it is to be understood that the mouth piece consti tuting the present invention can also be used as a part of a cigar or cigarette holder.

W hat is claimed is 1. In a tobacco pipe the combination with the bowl and stem, of a mouth piece having a transverse recess terminating the smoke passage in the mouth piece, and a soft rubber sleeve fitted snugly upon and extending `the smoke passage whenl the stein is subjected to suction bythe user.

2. In a tobacco pipe a mouth piecev having a transverse recess intersecting the smoke passage Within the stem,"said passage ter-k minatingvat the recess, a' soft elastic sleeve fitted snugly upon and extending'l'ongitudinallyofhthe mouthy ie'ce'and extending across' and 'normally c o sing 'the' recess, they rea portion of the sleeve beingadapted to expand when subjected to the action of suction` uponthe mouth piece bythe user; and al smoke spreading "flange upon theinner end of the mouthpiece and extending radially. beyond the innery end ofthe sleeve, said fiange constituting means for intercepting and spreadingsinoke ydrawn from thesl'eeve by. suction. l I

Thecombination with a tobacco pip'e,` of a -mouth "piece having'a transversereycess therein intersecting la portion of the smoke passage in the'mouth piece, said passage terminating atthe recess and saidfre- Icess having a fiat lWall entending to' the innery end of themouth piece, a soft' elastic;

` recess yand ,tobear upon the. `flat Wall vthereof, that portion of the sleeve-engaging the flat Wall ofthe recess being formed with a terminal notch or recess.

4Q The combination with a tobacco pipe, of a mouth piece having a transverse recess therein'. intersecting a lportion ofthe smoke passage in the mouth piece, said passage terminating at the recess and said recess having afiat lWall extending to the inner end of the mouth'piece a soft elastic sleeve fittedv snugly on and extending longitudinally of the mouth piece'andy normallycontracted Within the recess to close said recess andrv to bear. upon the Hat Wall thereof, and a con-y cavo-c'onvex 'smoke deflecting flange upon thel inner end of themo'uth piece and extending radially beyond the inner end of the sleeve, the concaved face' of the flange being nearest the. sleeve.

In testimonythat I claim the foregoing as my own, I have hereto affixedl iny'signature in the presencevof two Witness@ .Y f Y t WILLIAM It. DALES.
